Dobinsons Nitro Gas rear shock absorbers (part GS59-229) suit the Toyota Hilux N80 (2015 - 11/2025) leaf-sprung rear axle and are the value-focused twin tube option in the Dobinsons rear damper range. Nitrogen charging keeps the oil from aerating on long corrugated roads, so damping stays consistent when the tray or tub is loaded. Works with standard height and raised leaf spring packs. Sold as a matched pair at Dobinsons RRP, in stock in Australia with fitment support from our team.

Rear dampers on an N80 Hilux are one of the easier suspension jobs — upper and lower bolts only, with no spring compressor required because the rear is leaf sprung. Most owners or workshops complete the pair in under an hour. Support the axle before removing the old dampers so the leaf pack does not hang on the brake line. No wheel alignment is required for a rear damper change on its own.
Dobinsons has been designing and manufacturing 4WD suspension in Australia for decades, with damper valving developed for local loads, corrugations and touring distances rather than adapted from an overseas market spec. Every Dobinsons damper is backed by a manufacturer warranty. You can view the full Dobinsons range to match springs and other components to these dampers.
N80 owners replacing worn factory rear dampers, or matching new dampers to a set of raised leaf springs. If you tow a caravan regularly or run a heavy canopy full time, the IMS or MRA rear options handle sustained heat better. Pair with Dobinsons rear leaf springs if the rear end is sagging under constant load.

Yes — part GS59-229 is the Dobinsons rear damper for the Toyota Hilux N80 built from 2015 to 11/2025, across the 2.4L and 2.8L turbo diesel and 4.0L V6 petrol variants. The N80 uses a leaf-sprung rear axle and these bolt to the factory mounts. They do not suit the 2022-on Rogue or GR Sport wide-track models, or the N90 Hilux released 12/2025.
Yes. These rear dampers are valved and lengthed to work with the factory rear height and with Dobinsons raised leaf packs. The same rear damper part is used across the Dobinsons 2" and 3" rear lift specifications for this vehicle, so you do not need a different shock for each leaf option.
This listing includes a matched pair (2 x) of Dobinsons Nitro Gas rear shock absorbers, part number GS59-229. Leaf springs, U-bolt kits, bush kits and front dampers are sold separately.
It is worth considering. Front and rear dampers wear at different rates, but if the vehicle has high mileage on original dampers, replacing all four keeps the handling balanced front to rear. The matching Dobinsons front damper for the N80 is part GS59-228 in the same Nitro Gas range.
No. Changing rear dampers on a leaf-sprung rear axle does not alter suspension geometry, so no wheel alignment is required. If you also change leaf springs or lift the vehicle, then an alignment is needed because ride height affects front geometry.
